Many African cities lack reliable air quality data to inform their clean air measures. AirQo is scaling the deployment of open‑source, AI‑powered tools to help cities generate more reliable data and equip communities with air quality information.

New research spotlights the wider benefits of the UK's net zero policies, examining how cleaner air can drive improvements in public health, workforce productivity and quality of life across the country.

The global clean air initiative delivered with Clean Air Fund and C40 Cities receives further support from Bloomberg Philanthropies to build on early successes in 14 cities. With Addis Ababa and Madrid also joining the network, Breathe Cities is deepening its impact across five continents as demand rises for data-driven solutions to cut pollution and protect public health.

Clean Air Fund’s landmark programme is accelerating action on black carbon, a super pollutant that harms people’s health and drives climate change far beyond its share. With £10m funding from Wellcome, we will drive pioneering research and advocacy to deliver urgent health and climate benefits.

At the World Urban Forum, city leaders and international organisations adopted a new shared commitment to integrate air quality into urban planning. Supported by Clean Air Fund, this landmark global call to action embeds air pollution reduction at the centre of how cities are planned and designed.

Striking new images capture how black carbon pollution is harming communities and the environment, as well as solutions to reduce emissions. The photos are part of Climate Visuals’ new collection of over 200 free-to-use images, taken in Kenya, Nepal, Nigeria and Brazil.

New evidence shows climate models tend to misrepresent black carbon’s climate effects across highly polluted regions. The result is a potential bias that understates some of the super pollutant’s climate effects, which risks undermining mitigation efforts.

Philanthropic funding to improve air quality is stagnating, despite air pollution being the largest environmental threat to human health. Our latest research shows how targeted investments, especially in the world's most polluted regions, can make the greatest impact at a time of declining development assistance and increasing global challenges.

Clean air is good for our health and environment, but it’s also a growth strategy hiding in plain sight. When governments treat tackling air pollution as an economic tool, they can unlock higher productivity and huge financial savings.
